农村自杀者心理解剖条件Logistic回归分析

A Psychological Autopsy Study on Rural Suicides Using Conditional Logistic Regression Model

目的:应用心理解剖的方法探讨农村自杀的危险因素。方法:选择2000年-2001年辽宁省大连金州和庄河地区自杀死亡者66例,并按1:1选取对照组进行问卷调查。结果:本次研究的结果有3个因素作为自杀的重要危险因素保留在最后的方程中,分别为社会支持总分(OR=0.66,95%CI=0.48-0.91)、汉密顿抑郁总分(OR=1.18,95%CI=1.03-1.35)、神经症(OR=2594.59,95%CI=6.29-1069550)。结论:自杀并不是单一因素作用的结果,预防自杀要对多个因素共同干预。

Objective: To discuss the risk factors of suicide with psychological autopsy method. Methods: 66 complete suicides from Jinzhou and Zhuanghe of Dalian , LiaoNing province, which were individually matched with control population. Results: Three main risk factors of suicide remained in the final conditional logistic regression model. They were social support (OR = 0.66, 95%CI = 0.48 - 0.91 ), depression (OR=1.18, 95%CI=1.03-1.35) and neurosis (OR=2594.59,95%CI=6.29-1069550) . Conclusion: The combined effect of multiple factors increases the risk of suicide but not the unique effect of single factor. The suicide preventive efforts should focus on individuals exposed to multiple risk factors.
